The AnyTone AT-5555N II is a highly popular, modernized all-mode 10-meter transceiver known for its robust output and clean audio. For advanced operators, technicians, and hobbyists, accessing the service menu (also referred to as the engineering or alignment menu) is essential for fine-tuning the radio's internal parameters without opening the chassis.

While AnyTone frequently updates its firmware, the core alignment parameters in the AT-5555N II service menu cover several critical hardware functions. 1. Frequency Calibration (REF / FREQ)
